摘要： PURPOSE:To grasp a straightness shape in detail by installing three detectors which measure the distance from an object of measurement on a detector mount base at equal intervals, obtaining a measured value for every movement distance, and obtaining the straightness shape from data obtained by specific arithmetic. CONSTITUTION:Three displacement detectors A, B, and C are arranged on the detector mount base 3, and measured values are obtained at intervals of movement distance l/2 while the detectors are moved as shown by an arrow. Consequently, straightness errors are calculated at measurement objective points (ai) (i=2, 3, 4...) from one measurement data group of data obtained at the measurement objective points (ai) (i=0, 1, 2...). Similarly, straightness errors are obtained at measurement objective points (bi) (i=2, 3, 4...) from one measurement data group at measurement objective points (bi) (i=0, 1, 2...). The straightness shape of the object 1 of measurement is grasped in detail from the straightness errors at couples of measurement objective points.

摘要： PURPOSE:To reduce the friction coefficient and thrust between rolls, and to prevent bearing troubles, by shifting the timing of stopping the injection of a rolling oil during the idle time after a rolling material runs out of the rolls. CONSTITUTION:The period of feeding a rolling oil into an idle time is prolonged by 5 and 20 seconds even after the tail end of a rolling material runs out of rolls, and also the rolling oil sticking to the rolls is washed out by a roll cooling water, before the following material is bitten by the rolls, to increase friction coefficient. At that time, if said timing is prolonged by 25 seconds till the feed of oil is made off, the effect for washing out the oil is reduced, and slip is caused when the following material is bitten.

摘要： PURPOSE:To decrease the excessive thrust force acting on work rolls by providing power transmission devices which permit the movement of the work rolls in their axial direction in place of thrust bearing devices for the work rolls of a roll cross rolling mill. CONSTITUTION:A paired cross system is made into the construction wherein the thrusts of upper and lower work rolls 1, 2 are not supported. Power transmission devices 5, 6 which transmit torque and are adjustable in length, for example, splined shafts which absorb the axial movement of the work rolls, are provided. The upper work roll 1 and a backup roll 3 as well as the lower work roll 2 and a backup roll 4 are held in the positions where the axial centers are in parallel with each other and in this state the axial centers of the upper and lower paired rolls are crossed within the horizontal plane, and a plate material is rolled with such rolls. If relative slips are to arise in the axial direction between the work rolls and the plate, the rolls 1, 2 move axially so as not to apply any relative slip on the plate W.

摘要： PURPOSE:To reduce warp of a plate and to decrease a deviation of plate thickness, by executing a reduction at a reduction rate for inhibiting the generation of warp while a warp part of a rolling material is rolled by a different diameter roll, and setting it to a regular reduction rate after the tip of the rolling material is bitten into the following stand. CONSTITUTION:In a rolling mill having an upper work roll 2 of a small diameter and a lower work roll 3 of a large diameter, a gap of the rolls 2, 3 is set to a value for reducing the warp of the tip in the bitting limit in case of bitting of the tip of a rolling material 1, and after the tip of the rolling material 1 comes out of the rolling mill by prescribed length, the roll gap is set to a value for reducing a non-tension off-gauge and a deviation of plate thickness is reduced, to the part whose warp does not become a problem. After the tip of the rolling material 1 is bitten into the following rolling mill, said gap is set to a regular roll gap. Also, the surface roughness of the large diameter roll 3 is smaller than that of the samll diameter roll 2, or the face corresponding to the outside of warp of at least the top part of the rolling material is made higher in its lubrication than that of other face, or the like, by which generation of warp of the top part can be inhibited to some extent.

摘要： PURPOSE:To provide a titled device prevented from the deviation of a pass- line adjusting liner and abrasions, etc., by providing a sliding base moving with both of a lower back-up roll chock and the pass-line adjusting liner in one body. CONSTITUTION:In a cross rolling mill, rolling a plate material 1 by work rolls 2 and 2' and back-up rolls 3 and 3', both of a pass-line adjusting liner 15 and a horizontally movable sliding base 14 are inserted between a lower back-up roll chock 7' and a bottom beam 21'. In cross rolling action, as lower cross beams 22', driven by jacks 13a', 13b', 13c', and 13d' used for the lower roll, touch both the roll chock 7' and the sliding base 14 at the same time and move both the members together with the liner 15 in one body, a generation of relatively slipping phenomenon between these members is avoided.

摘要： PURPOSE:To obtain a good sheared shape and enlarge the range of allowable deviation between a workpiece and shearing cutters, by restricting the increase in the width of the sheared portion of the workpiece of square cross section in the shearing of the workpiece. CONSTITUTION:The square cross section of a workpiece 1 has four sides 1a-1d. After the workpiece 1 is conveyed in, an upper tool holder 4 is moved down in the direction of an arrow 6 by a driver to shear the workpiece 1 while restricting the increase in the width of the workpiece by the restraining edges 2b, 3b of an upper and a lower cutters 2, 3. The shape of the sheared portion of the workpiece 1 after the shearing is within that of the sheared portion before the shearing, as shown by a full line (a chain line shows the cross section of the workpiece before the shearing). For these reasons, the workpiece 1 is sheared to the proper shape and the range of allowable deviation between the workpiece 1 and the shearing cutters 2, 3 can be widened.

摘要： PURPOSE:To obtain a fine cross section without deformation and make unnecessary correction after shearing by shearing material to be processed by cramping the material on its sides according to its shape. CONSTITUTION:An upper shearing cutter 2 and a lower shearing cutter 3 are so arranged that they are movable, and cramping mambers 5, 7 are attached to the cutters in such a way that both the cutters and members form an integrated part. A material 1 to be processed with a rectangular cross section, which is continuously sent in, is allowed to contact position detecting movable pinch rolls 10, 11. Thereby detectors 14, 17 operate oil hydraulic cylinders 8, 9, while the cramping members 5, 7 cramp the material 1 to be processed. Thus, the material 1 to be processed is shown by the shearing cutters without deformation in such a state that the material is firmly cramped.

摘要： PURPOSE:To prevent unsatisfactory shearing effect and to improve the rate of operation of a mill by setting the radii of rotation from tops of upper an lower blades, which are mounted on upper and lower rotary drums, to the center of each drum different and setting the angle speed of the rotating drum the same. CONSTITUTION:A radius of rotation from the center 01 of an upper drum 2 of a drum type shear to the top of an upper blade 3 is set to be (r1), and a radius of rotation from the center 02 of a lower drum 4 to the top of a lower blade 5 is set to be (r2), and the radii of rotation is designed to be r1>r2, and the rotating angle speed theta of both upper and lower drums are set to be the same. When material 1 is fed in the direction shown by an arrow and the drum is turned in the direction shown by an arrow, the material 1 is pushed downward and bent when the upper blade 3 first touches the material 1, so that a bending angle of a crop becomes smaller and desirable shearing effect can be obtained in cooperation with the lower blade.
